Evra is a reported target for Crystal Palace and Valencia and has sat out Juve's two matches following the winter break - a Serie A victory over Bologna and a midweek Coppa Italia win against Atalanta.

He will again be missing as the Bianconeri go to Fiorentina on Sunday night but his absence has been sanctioned by Allegri.

"Evra, besides being a great professional, is a great person," the trainer told reporters.

"We talked quietly together, he is considering what to do, and this situation creates absolutely no problem or any disturbance."

Juve sit four points clear at the Serie A summit with a game in hand and, while happy with their progress, Allegri warned there is still much work to do over the second half of the season.

"We have done some good things this season," he said. "But the important thing is to concede fewer goals. On Sunday we are facing a side that loves to shoot from distance, as they've got players who can do that from all angles.

"We can also improve on our passing, the way we command the game and to defend when it's necessary. There's no shame in that, football is about defending and attacking. That has to be the next step in our journey.

"If we retain our current lead over the next four games then we'll have a very good chance of taking home the Scudetto."

Fiorentina and Juventus share a keen rivalry and Allegri is aware of the importance of the fixture to Sunday's opponents.

"It’s always the game of the year for Fiorentina and I hope for a great evening of sport, including in the stands," he said.
